SOLVED: FACTURE_ENABLE_NEGATIVE_LINES

Hello,
how to set this option to 1?
Thank you

Hello

Where did you find that constant? It is not listed on the Setup Other page

In an invoice, when I try to add a line with negative value, the alert in picture is displayed. I’m using 8.0.3
In previous versions it was possible.

Pièces jointes :

Try:

Home ► Setup ► Other

FACTURE_ENABLE_NEGATIVE_LINES = 1

Let me know if it works and then I will add it to the wiki

Yes, it runs!
Thank you
ciao

Excellent… could you please send a screenshot of the ‘negative’ lines? It will help me add the description to the wiki for this setting
